Not sure if this is helpful information, but yeah, I did that, because ycombinator is very buggy. Try posting without having an account from mobile. Website asks you to type login and password, then says that such account already exists and you need to create a new one. What I did not know, it was creating accounts and posting without my knowledge. Have a good day.
